I have 13+ Years of experience in Mainframe - Development and Manual testing - TEST Mainframe Environment setup for batch job processing ,manage & maintenance. To up skill my self, would like to pursue course in Mainframe System Administration. Is it a good choice where there is lot of buzz around the new technologies/careers like Data Science, Big Data, IoT..etc? Does MF System Administration has market for people like me who's switching career (Mid of their life) from Batch job/TEST Environment setup specialist to mainframe administration? What are the industry expectations/standards with respect to Mainframe System Administration? Also is there a institute who can provide unlimited virtual lab facility and online training?
